Web Content Accessibility Guidelines (WCAG)

What you need to know

The Web Content Accessibility Guidelines (WCAG) are internationally recognized standards developed by the World Wide Web Consortium (W3C) to make digital content accessible to people with disabilities.

WCAG guidelines are organized into three levels of conformance: A (minimum), AA (intermediate), and AAA (highest). Most organizations and legal requirements target WCAG 2.1 Level AA compliance as their standard.

WCAG compliance is crucial for legal compliance with various accessibility laws worldwide, including the ADA in the United States, AODA in Ontario, and EN 301 549 in the European Union.

Core Principles

WCAG is built on four fundamental principles that ensure web content is accessible to all users. These principles are known by the acronym POUR:

1. Perceivable - Information must be presentable in ways all users can perceive
2. Operable - Interface components must be operable by all users
3. Understandable - Information and interface operation must be understandable
4. Robust - Content must be robust enough to work with various assistive technologies

These principles form the foundation for all WCAG success criteria and ensure digital content is accessible to users with various disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities.

Meeting WCAG Standards

To achieve WCAG compliance, websites and applications must address the following key areas:

1. Provide text alternatives for non-text content
2. Create content that can be presented in different ways
3. Make all functionality available from a keyboard
4. Provide users enough time to read and use content
5. Help users navigate and find content
6. Make text content readable and understandable
7. Make content appear and operate in predictable ways
8. Help users avoid and correct mistakes

WCAG guidelines are technology-agnostic, meaning they can be applied to different web technologies and continue to be relevant as technology evolves.
